JOHN GOOD, OF FAR ROCKWAY, NEW YORK.

SPINNING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 541,271, dated J' une18, 1895.

Application filed September 27, 1894. Serial No. 524,223. (No model.)

To all whom, it may concern.E

Be it known that I, JOHN GoD,of Far Rockaway, in the county of Queensand State of New York, have invented a new and useful Improvement inSpinning-Machines, of which the following is a specification.

This invention relates more particularly to a spinning machine of thekind known as the jenny used for the spinning of twine and of yarns forcordage, and the object of the improvement is to simplify the machineand to enable it to be driven at a higher speed than has hitherto beenpracticable.

The nature of the improvement will be described with reference to theaccompanying drawings and its novelty will be set forth inl the claims.

Figures l and l* represent together a side elevation, partly in section,of a machine embodying my invention; Fig. 2, an elevation of the drivingend ofthe machine; Fig. 3, a transverse vertical section in the line 3 8of Fig. l; Fig. 4, a transverse vertical section in the line 4 4 of Fig.l; Fig. 5, a central longitudinal sec tional View of the bobbin andflier and their immediate appurtenances; Fig. 6, a central longitudinalsectional view of the friction device which produces the draft on theyarn or twine between the bobbin and the flier. Figs. 7 and 8 are`detailviews which will be hereinafter explained. Fig. 9 represents atransverse vertical section'of the machine in the line 9 9 of Fig. 1*.

Similar letters and figures of reference designate corresponding partsin the several tignres.

A is the framing of the machine.

B is the main shaft arranged at one end of the framing transverselythereto and lfurnished with fast and loose pulleys C C which receivemotion through the main beltD which is shipped from one of said pulleysvto the other by a belt-shipper D. v

E is a horizontal shaft running lengthwise of the machine and derivingmotion from the main shaft B through bevel gears a b. This shaft Ecarries a pulley F for driving the iier N N', a pulley G for driving thebobbin P and an endless screw H for driving the chains I which carry thegill-pins c c; the said endless screw H gearing with and drivingaworm-gear J on a transversely arranged shaft K which carries a pulleyLfrom which a belt L runs to and drives a pulley M on the driving shaftd' of the gill-pin chains I.

The flier N N herein represented consists of a cylinder open at one endand closed at the other end by which it is attached to its journal ewhich runs in two journal boxes e on the top of the framing and isfurnished with a pulley e2 to receive the driving belt F from the pulleyF. This cylindrical flier is represented as composed of a metal disk Nand cylindrical shell N attached at one end to said disk. Thiscylindrical shell I make of a piece of seamless paper tubing becausethat material is very cheap and enables a flier having the necessarystiiness and strength' to resist the elects of centrifugal force to bemade of less weight than a metal flier of cylindrical form and thereforeto be run at a higher speed and with less wear of jour` nals and tobemore'easily stopped when run at a high velocity. The metal disk N isrepresented (see Fig. as-formed with a rim projecting from its facesubstantially parallel with Vits axis for the purpose of attaching theshell N which fits tightly over the said rim and is attached thereto inany suitable and secure manner as by screws f. The hier thus constructedis furnished internally with sheaves g, 71, t' for guiding the yarn fromits eye j to the bobbin. The sheavesi which are arranged near the mouthof the flier and are attached to the shell N of paper or light material,are pivoted in metal angle pieces t" which are riveted or securedA tothe shell as indicated at i2 in Fig. 3. The journal e of this hier mayhave a capstan head e3 of any known or suitable kind. 5

The bobbin P is represented as carried and driven in a well known mannerby a central supporting spindle la and a hollow driving spindle Z,through which said spindle k passes freely, the said spindle Z beingfurnished with the pulley lo' receiving Athe driving belt G from thepulley G. The driving spindle Z runs in bearings 7a2 in a carriage Pwhich is fitted to slide in a direction lengthwise of the spindle inways k3 on the top of the framing. lVhen in operation the supportingspindle k is supported at itsinner end, as shown 'at m in Fig. 5,in abearing in the inner end of the flier journal, but it is alwayssupported both I 1 hanger p' secured to the sliding carriage P',

in the hollow driving spindle l and in a fixed bearing in a small standn on the top of the framing. This stand fn is fitted as shown in Figs. land 2, with a vertically sliding bolt 'n' which abuts against the outerend of the spindle lr, when the said spindle is in its operativeposition and so locks it. This arrangement of the supporting spindle kand the means of locking it endwise are not new and are only heredescribed as leading to the further explanation which will behereinafter made of the means of simultaneously locking the said spindleandthe traverse screw Q and y simultaneously unlockingthem.

The traverse screw Q turns in a box p in a the said box containing theusual switch nut for workingl eitherin the right hand or in the lefthandthread of the said screw. The shaft of said screw also fits in bearingsin two sta- 'tionary hangers p2 p3 dependent from the framing A, and itis capableof sliding lengthwise outward through and beyond `the saidbearing in p2. The said shaft is furnished with a bevel gear p4 whichgears Awith a bevel gear q on the upper end of an upright shaft q, whichturns in a bearing in the bottom of the hanger psand a second bearingg5secured.

to one of the journal-boxes of the shaft K, the said-shaft beingfurnished on its lower part with va bevel gear q2 which gears with abevel gear g3 on the transverse shaft K hereinbefore described, the saidbevel.v gear g3, shaft q and bevel gears q and p4, thus driving thetraverse screw. lheltra'verse screw when in operation is confinedlongitudinally between Y its bearings in the hanger p3 and a downwardprojection fr on a hand-lever R (see Figs. l and 2) which works on afixed fulcrum'fr in the end of the framing outside the hanger p2. Alaterally projecting arm of this y lever is connected as shown in Fig.V2, by a slot and pin connection 'r2 with the fsliding bolt n which locksthe bobbn supporting spindle k in place. In the normal position to whichthis lever is brought by the weight of its laterally projectingV arm andof the sliding bolt n', the said bolt abuts against Yand acts as a stopto lock the spindle 7c and at the same time the projection fr on thehand-lever forms an abutment anda stop to the outer end of the traversescrew and both the said spindle and the screw are locked endwise whilethe machine is in operation and until it is desired to remove the bobbinwhen .the hand-lever is brought lo a position to uncover the outer endsofthe said spindle and screw and allow both the said spindle and screwto be drawn outward, the drawing outward of the screw being necessary topermit the drawing back of the carriage P and spindle Z to draw thebobbin out ot' the flier, because the screw is always engaged with thesaid carriage bythe switch nut in the box p.

S (Figs. l and 6) is the friction disk for producing the draft on theyarn between the flier and the bobbin. This friction disk is applied onthe shaft E and operates against one side of the bobbin driving pulleyG.

The said disk is formed upon or rigidly se-` thereon but it is heldagainst the friction disk S in such manner as to be capable of beingturned by the friction thereof by means of acoil-spring t whichsurrounds the sleeve S wherever lit is incased by a. box S2 and 'heldabutting against the said spring by nets t fitted to a screw thread onthe sleeve. screwing up these nuts the spring tis adjusted to exert agreater or less Vpressure against the pulley and so toV adjust thefriction which the'said pulley receives from the disk S and therebyadjust the draft on the yarn as t-he flier is driven positively by thepulley F on the shaft E, While the bobbin is driven by the frictiouofthe said disk S. The sleeve S is .jonrnaled, as shown at s2 in Fig. 6,into a rigid hanger P2 dependent froln the "bobbi'n carriage P', in suchmanner that the said sleeve may turn freely in said hanger but iscompelled by it to move with the said` carriage in the traverse movementof the bobbin and so to carry thepnlley G and the'triction disk back andforth along the shaft E and keep the pulley G and belt G always inproper relation `to the bobbin pulley k.

The condenser T represented kin Fig. 1 may vbe of any known or suitable'kind and therefore needsno particular description.

The machine is fitted with a stop motion IOC which provides for stoppingit automatically and almost instantaneously under thefollowingcircumstances, viz: first, in case of interruption of thesupply of sliver toY thecha'ins of gill-pins; second, in case ofthe yarnor twine breaking or being interrupted between the vflier and thecondenser orgill'pi'ns; third,`

The stop shaft U which Vextends as shown in Fig. l, from the driving endof tliemachine to a little beyond the head of the flier is fur nishedwith a hand-lever U (Figs. l and 4) which may be termed the stop lever.The said shaft is also furnished with an arm u' (Figs. l and 2)connected with and operating the belt-*shipper D', andis'iurtherfurnished with an arm u2 (Figs. l and 3) for throwing and holding offthe brake F2 from the flier driving pulley F, and with a cam u8 (Figs.1,

2 and 7) forthrowing and holding of the brake rod a4 connected with it,another arm carry-- ing the brake shoe @t5 which acts on the inside ofthe rim of the pulley F, and the third arm being connected with theframing A by the spring u@ which always tends to p ut the brake inoperation and at the same time act-- ing through the brake lever, therod n4 and the arm u2 of the stop shaft U, always tends to turn the saidshaft in a direction to make its arm u' ship the main belt from the fastpulley C to the loose pulley C. This action of the said spring iscounteracted, when'the machine is in proper operation, by means of asmall lever W which I call the locking lever, which is furnished with ahook w which hooks over a projection w on the hand lever and so holdsthe said lever in a position to keep the brake F2 out of operation andto hold the belt-shipper in position to keep the belt on the fastpulley.

The brake Gr2 of the bobbin driving pulley G which is shown in Fig. 2buty more clearly in the separate view Fig. 7, has to move with the saidpulley along the shaft E and therefore it is attached to thebobbin-carriage.

The said brake G2 consists of a lever, the fulcrum 13 of which isaffixed to the'hanger P2, one arm of the said lever constituting thebrake shoe and operating on the outer periphery of the said pulley andthe other arm being connected with the said hanger by a spring yu whichexerts a constant tendency to apply the brake to the pulley but theaction of which, when the machineis in proper operation, is counteractedby the cam us before mentioned on the stop shaft U. This cam must be ofa length in the direction of the length of the stop shaft, as shown inFig. 1, a little greater than the length of the bobbin traverse in orderthat it may remain operative in all positions of the bobbin.

The tripping shaft V which extends (as shown in Figs. 1 and 1*) from aposition in rear'of the chains I to a position some distance beyond thefrontend of the flier, is furnished with an arm v2 (Figs. 1 and 9), ahooklike cam v3 (Figs. 1 and 4), which may be termed the tripping camland with an eccentric-like arm o4 (Figs. 1 and 3). vThe arm U2 whiehvisat the rear end of the tripping shaft has a crank-pin 14 which isreceived in alink or fork 15 on the lower end of a rod 16 which issuspended from one of two levers 17 in which is journalerl the upper oneof the feed 4 rollers 18,18%' for feeding the'sliver to the chains l ofthe gill-pins c, the said levers having affixed fulerum 19 and being soproportioned that a very slight upward and downward movement of the feedroller 18* produces a very considerable rise and fall of the rod 16.While there is a proper supply of sliver to the feed rollers 18, 18* therod 16 is so held up that its link orrfork leaves the wrist-pin 14 ofthe arm U2 of the tripping shaft free and the tripping shaft is heldagainst any tendency to turn accidentally in the direction of the arrowshown near it in Fig. 4, by the engagement of its tripping cam 'v3 witha small projection 20, preferably con-l sisting of a friction roller, onthe hooked locking lever )V which is then itself 'locked by theengagement of its hook w with the projection w on the hand-lever U; butwhen the supply of sliver to the rollers 18, 18* isinterrupted, theroller 18* comes down so low that by its action through the levers 17andithe rod 16, the upper end of 'the link 15 ofth'e said rod will beardown on the arm 'v2 of the tripping shaft V andthe said shaft willthereby be caused to turn in the direction of the arrow shown neaf'litin Fig.4. The tripping cam U3 then, by its action against the projec-Ytion or roller 20 on the locking lever lV, will lift or trip the saidlever clear of the pr0jection w on the stoplever V', and so liberate thestop lever and leave the stop shaft free to the action of the spring uby which the main belt D is shipped to the loose pulley andthe brakesare brought into operation to stop the flier and the bobbin almostinstantaneously. It will be understood that as the traverse screw andthe gill-.pin chains are driven from the same shaft F as the flier andbobbin, all will be stopped together and at the same time the feedrollers 18, 18* will be stopped as these rollersare driven by a belt 21running to a pulley 22 on the roller 18 from a pulley 23 on the chainYshaft 24.

For the purpose of causing the stoppage of the machine by adisengagement of the lockingV lever W from the stop lever U, similar tothat above described, Whenever the yarn or twine is broken orinterrupted between the `filer head and .the condenser or the gill-pinchains, the locking lever is furnished with an upward prolongation 25toward the iiierhead e3, as shown in' Fig. 4, and there is provided inthe flier head opposite this prolongatioma centrifugal tripping tappet Yconsisting of a short pin which is fitted loosely within and projectsthrough a hole or mortise bored or cut transversely through the flierhead. ln this tappet there is a hole 28large enough for the yarn ortwine 4to pass freely through. One of the projecting ends ofthe saidtappet is represented as provided with a head 2G and the other as havinga pin 27 inserted through -it to prevent it from coming altogether outof the hier head, and one endfor instance that which has the head, ismade heavier than the other-so that when the flier is in motion thecentrifugal force developed in the Said tappet will tend tomake thetappet fly out in onedirection from the -fiier head, .bntwhile there isany yarn or thread ICO lIO

passing through the hole .in the tappetfthat will counteract thistendency. When, however, the yarn or twine is broken or interruptedthere will be no restraint to the centrifugal tendency and the tappetwill instantly fly out far enough to strike the prolongation 25 of thelocking lever W and so to throw the said lookin g lever out ofengagement with the stop lever U and leave the stop shaft free to theaction of the spring 'a6 which produces the stoppage of the machine asbefore'eX- plained.

The eccentric-like arm 'U4 (Fig. 3) on the tripping shaft V is for thepurpose of stopping the machine when the proper quantity of yarn or'twine has been spun on to the bobbin'P. This arm c4 is situated nearthe mouth or open end of .the flier and in such position (see Fig. 3)that when the tripping shaft is in position for the proper operation ofthe machine, the heads of the bobbin may pass clear of the said arm topermit the bobbin to pass into the flier. When a body of yarn on thebobbin arrives at a certain circumference, its outer coils will comeagainst and so press down the said arm and turn the tripping shaft V asto produce the action of the tripping cam v3 on the locking lever. ashereinbefore described for disengaging the stop lever and causing thestoppage of the machine. It may be here mentioned that the arm v4 is notnecessarily of eccentric-like form but is merely made round to preventany loose portions or fibers of the yarn from catching on it.

After the machine has been automatically stopped in any of the wayshereinabove described or after it has been stopped under anycircumstances and when it has -been again started by pulling outward thestop lever U by hand and thereby shipping the belt D on to the fastpulley C and throwing ont' the brake F2, the locking lever W is operatedby hand to re-engage with the projection w on the stop lever and lockthe latter lever. By this re-engaging movement of the locking lever theprojection 2O on the said lever is made to so act upon the tripping camu3 as to turn the tripping shaft into the position in which it is readyto trip the locking lever W by the filling up of the bobbin or bytheinterruption of the sliver between the feed rollers 18, i8* in whichposition also thecam a3 on the said shaft also holds the spindle pulleybrake Gr2 out of operation. the locking lever brings its upper arm 25into position to be operated by the action of the centrifugal fliertappet as hereinbefore described.
